EMP-Protectors USN Series

The USN-series is designed to provide protection against surge and interference voltages as feed-through type mechanical unit for data and control line systems. Depending on the specific application different types are availble. The highly effective multi-stage transient protection design combined with filtering components provides excellent protection against the effects of atmospheric discharges (lightning, electrostatic discharge) or a High Altitude Electro-Magnetic Pulse (HEMP), sometimes also referred to as Nuclear Electro-Magnetic Pulse (NEMP) or simply EMP. Special features of this series of protection circuits include high surge current capability, compact feed-through design and simple installation directly to Faraday cage. The USN-Series will be threat-level tested against EMP according to MIL-STD-188-125, short pulse and intermediate pulse.

USN-22001 2 * VDSL / ADSL / ISDN / POTS

Meteolabor® USN-22001 protects two telephone wire pairs of analog or digital telephone subscriber lines (POTS, ISDN,DSL, ADSL, VDSL) against the effects of lightning and EMP.USN-22001 has pluggable WAGO MCS Micro terminalblocks with locking levers and CAGE CLAMP® contacts. Thewires are easy to install by using the supplied operating toolor a matching screw driver.For best protection results a feed-through installation froman unprotected volume into a shielded and protected roomis recommended.USN-22001 protector/filter is designed to be used in fixedinstallations (buildings, underground shelters etc.) as well asin portable and mobile systems like containers or sheltersand vehicles, which need to be EMP-tested according toRS105 of MIL-STD-461F. Datasheet USN-22001

USN-40001 10/100 Mbps Ethernet

Meteolabor® USN-40001 combines the protection of twopieces Meteolabor® USS-2-AQ in one case to provideexcellent protection for two twisted pairs of a 10/100 Mbit/sEthernet connection of sensitive electronics such ascomputers, telecommunication equipment etc. against theeffects of lightning and EMP.USN-40001 has shielded RJ45 jacks and can be easilyinstalled by using of-the-shelf patch cables. For best resultsshielded cables are recommended.Input and output of USN-40001 are isolated by a magneticcircuit which provides best protection and filtering effect in afeed-through installation from an unprotected volume into ashielded and protected room. However, PoE (Power overEthernet) is not possible with USN-40001.USN-40001 protector/filter is designed to be used in fixedinstallations (buildings, underground shelters etc.) as well asin portable and mobile systems like containers or sheltersand vehicles, which need to be EMP-tested according toRS105 of MIL-STD-461F. Datasheet USN-40001

USN-40002 Surge Protector / Filter RS422 / RS485 / PROFIBUS

Meteolabor® USN-40002 protects two wire pairs of RS422 /RS485 / PROFIBUS interfaces against the effects of lightningand EMP. It replaces the Meteolabor® USS-4-RS422/485/FDin a much smaller case and has even better performance.USN-40002 has pluggable WAGO MCS Micro terminalblocks with locking levers and CAGE CLAMP® contacts. Thewires are easy to install by using the supplied operating toolor a matching screw driver.For best protection results a feed-through installation froman unprotected volume into a shielded and protected roomis recommended.USN-40002 protector/filter is designed to be used in fixedinstallations (buildings, underground shelters etc.) as well asin portable and mobile systems like containers or sheltersand vehicles, which need to be EMP-tested according toRS105 of MIL-STD-461F. Datasheet USN-40002

USN-80001 EMP Surge Protector / Filter 10/100/1000 Mb/s Ethernet

Meteolabor® USN-80001 protects all four twisted pairs of a10/100/1000 Mbit/s Ethernet connection of sensitiveelectronics such as computers, telecommunicationequipment etc. against the effects of lightning and EMP.USN-80001 has shielded RJ45 jacks and can be easilyinstalled by using of-the-shelf patch cables. For best resultshielded cables and a feed-through installation from anunprotected volume into a shielded and protected room arerecommended.USN-80001 also transmits up to 50V DC and can be used forPoE applications according to IEEE 802.3af.USN-80001 protector/filter is designed to be used in fixedinstallations (buildings, underground shelters etc.) as well asin portable and mobile systems like containers or sheltersand vehicles, which need to be EMP-tested according toRS105 of MIL-STD-461F.  Datasheet USN-80001
